|Woofer-Hi-Definitioner(WHD & STAND)||Woofer-Hi-Definitioner-pure(WHDPURE)|
|The main structure;
1. Wooden cabinet black and frosting painting.
2. Four places of the horn made of brass are fixed to the front.
3. 18kHz or less are efficiently cut by a structural wave-like polymer
piezoelectric bimorph vibration board arranged in a horn central base point.
4. A large gold-plated speaker terminal is fixed to the back.
a. The peel line can be inserted and be passeed through the hole
on the terminal side. The screw can stop it.
(The maximum diamete of line is 5mm)
b. Moreover, the banana plugs can be inserted in the back of
the speaker terminals
5.The aluminum rotary switch is adhered to the center of the back,
and both terminals of +- have been partitioned in the insulation version.
Efficiency is switched to five stages.
6.There is a transformer in the inside, and the voltage input to both speaker
terminal is pressured to 25 times. So as not to get an electric shock even
if touching, the outside of the cabinet is insulated.
(However, feel after the speaker terminal after turning off the power supply
of the amplifier because the usual voltage input from the amplifier hangs
just like a usual speakers)
7. The four places of bottom are supported by the foot made of brass
with the reverse-conic.
|The main specification;|
|1.Maximum rating; The protection circuit operates over 100V(However, the test signal by 20kHz or more
: shoud be under 20V). It return to the origin when you turns off power and
a few minutes pass. )
2.Impedance; infinity-140Ω-28Ω(direct current-20kHz-100kHz).
3.Reproduction frequency; It is cut steeply under 18kHz with Heil type structure and capacitor.
4.maximum output sound pressure; 100dB/W/m( Efficiency is switched to five stages)
5.Mass; About 720 grams
6.Size; About 110mm (width)70mm (height)100mm (terminals are not contained) and 23mm(terminal depth)
7.Drive system; TAT-driver(Heil type baimolf polymer piezo-electric driver)
|Explanation of rotary switch;|
|When the black round sign position of the rotary switch in the back is switched.
It is the efficiency of the speaker and revokable at five stages.
|OFF ； 70dB
1 ； 85dB
2 ； 90dB
3 ； 95dB
4 ； 100dB
|The position of turning off is not turning off
in completely but 70dB .
|Switch position of rotary switch|
|Note; Setting position lower than the efficiency of the main speaker is often achieved a better effect and exists.|
